Special cement for commercial concrete and production process thereof
The invention discloses special cement for commercial concrete, which is prepared from the following components in percentage by mass: 60.0 to 68.0 percent of medium alkali clinker, 4.0 to 6.0 percent of desulfurized gypsum, 8.5 to 11.5 percent of slag, 12.0 to 18.0 percent of waste stone powder, 5.0 to 7.0 percent of fly ash and 0.08 to 0.12 percent of efficient grinding aid, and discloses a production process of the special cement. The invention relates to the technical field of cement production and processing, and particularly provides special cement for commercial concrete and a production process thereof, by adding medium-alkali clinker, slag, waste stone powder and fly ash, the addition amount of building sand is reduced, the requirement of commercial concrete for reducing the addition amount of additives is met, the special cement for commercial concrete meets the requirements of mass concrete engineering, and the fluidity, workability and water demand of the special cement for commercial concrete produced by the invention are superior to those of same-grade ordinary Portland cement.
本发明公开了一种商砼专用水泥，包括下列质量占比的组分：中碱熟料60.0～68.0％、脱硫石膏4.0～6.0％、矿渣8.5～11.5％、废石粉12.0～18.0％、粉煤灰5.0～7.0％、高效助磨剂0.08～0.12％，并公开了其生产工艺。本发明涉及水泥生产加工技术领域，具体提供了一种商砼专用水泥及其生产工艺，通过采用中碱熟料、矿渣、废石粉、粉煤灰的添加，降低了建筑用砂的添加量，且在满足商品混凝土对于降低外加剂掺加量的需求同时，满足大体积混凝土工程的需要，且本发明生产的商砼专用水泥的流动度、和易性、需水量方面都优于同级普通硅酸盐水泥。
